At least 200 were injured in Suffolk where a twister destroyed several homes and businesses, said Bob Spieldenner of the Virginia Department of Emergency Management.

The storm hit the 138-bed Sentara Obici Hospital, though Spieldenner said the facility was still operational and accepting patients.

A second tornado struck Colonial Heights -- about 60 miles northwest, near Richmond -- injuring at least 18 people, he said.

A third twister damaged several homes near Lawrenceville, about 70 miles south of Richmond, said Bryan Jackson, a meteorologist with the National Weather Service, which confirmed all three tornadoes.

Gov. Tim Kaine declared a Virginia-wide state of emergency as hazardous weather continued through the central part of the state.

The Suffolk twister touched down just before 4 p.m. ET and plowed its way east into Norfolk, damaging scores of homes, stores and cars and downing dozens of trees and power lines, Jackson said. Watch as a witness describes the tornado form »
